Q100/AKM hub motor can be bought from BMS Battery or Topbikekit both China based.

You and I and possibly the rest of us may be talking cross purposes when insurance is mentioned. You are talking of theft insurance which is possible for any bike, on the other hand I and some of the other responders are taking about legality insurance, I.e. whether or not you can get 3rd party...

As years advance the software can change so it is possible that the light is always on and might be a safety feature. The fact the bike appears to be working is good news, problem with controllers is that you can only test for a few main faults once they have been exhausted the minute parts are...

Answer is no, so buy a new PAS sensor with three wires. They are cheap enough to buy to do the job properly.

For endless range leave the assist off, next best option is to use the lowest assist level you can get away with. If it means using a higher assist for inclines then so be it, but go lower asap when you can. Cadence won't matter, it is what you are happier with. Selecting the best gear not to...

Just because you can get insurance for an e-bike doesn't mean it is road legal as a pedelec, some will need to be SVA'd & reg'd in the light moped class. And certainly aren't allowed on paths or on off road routes except for byways where permission is allowed.

Covering the whole camper roof with panels for on the move and if needed some more to plug in when camped up ? As you say you will have to do the math to see if the batteries can supply the demand you require for your camper van needs. The deep cycle batteries opposed to Lithium prefer to stand...

For all bar the bikes how about considering solar charging on the move and when stationery, using deep cycle SLA batteries ?

A hub bike in my view is a better commute option, it looks nicer with the hub in the rear wheel. The clunky mid drive look is just down right ugly with its horrible bulky looking BB area which once would have had a tidy look to it and sticks out like a sore thumb. For commuting you need the...

Hard to say but sounds like no power is coming out of the battery could be an internal fuse blown, not to sure if you will be able to get a good voltage reading or not from the discharge pins.

20mph+ continually is possible with the added advantage of assist level being above the cut off, ideally a 48v system will be better as would an S -pedelecs. Keeping a high speed above the 15.5mph cut off will be tiring so you will need to de-restrict. 328rpm will be the way to go but you will...

If it has the looped Blue wire then Cruise is set in auto mode and can not be disabled, you will need to access the controller and disconnect it. The C7 option only works if it is unconnected.

Ok thanks for clarifying, it sounds like the freehub pawls are sticking and not correctly engaging. Likely that any grease has got a bit thicker /solidified some what due to the cold weather or maybe moisture ingress has caused rusting in the area causing stiffness/sticking. On the end of the...

Are you saying the bikes cassette gears do not freewheel backwards very well and they are sticking/ catching some times ?

I can feel the hubs cutting in & out on my bikes which have used Bafang BPM & CST, AKM128 and a Yose hub.

With ebike hub motors freehub bodies that are removeable are quite simple to do, if this is not the case then it will be designed as non removable part. Point in case is the Q128c the freehub body isn't removable but a replacement side cover plate with freehub body is available, the bafang CST...

All personnel details/info inc phone, bank email, etc,etc should be done in a private conversation. Use the envelope icon top right between your user name & bell icon.

I think a typo 43v :eek: ? 2 -3v sag can be par depending on the cells, P configuration and current drawn.

If the bike is the one on Facey thing then it has an illegal D/D hub which will be likely 1kw or more.

It isn't uncommon for batteries to spark when charging/plugging in. Without the battery being opened there's little chance of seeing if any damage has been done. Firstly though you need to check the voltage at the battery discharge contacts with a meter to verify the actual voltage output.
